Accessory Dwelling Unit (ADU) Permit in Rifle, Colorado

A permit is required for ADU construction within Rifle city limits, per the City's Residential Information page, which explicitly lists 'ADU's' among the work types requiring a residential permit. Beyond that permit requirement, no published City source sets out Rifle's ADU-specific zoning standards — size caps, setbacks, parking, or design requirements — so confirm those with the City before designing to them.

Tips

  • Rifle names ADUs as requiring a permit, but posts no public-facing ADU zoning standards page (size caps, parking, setbacks) the way Glenwood Springs publishes one — confirm zoning-specific ADU standards with Community Development (970-665-6499, Zach Higgins) before designing a unit.
